What we look for
Raptor followed the redirects (rules that forward one address to another) from these addresses and came back to an address it had already passed through.
Why it matters
Search engines stop following a loop, so the page these addresses should lead to cannot be reached or listed through them.
How to fix
Correct the redirect rules in your server, CDN or CMS settings so each address forwards once, straight to a page that loads. Then point links at that final address.
What it cannot know
Raptor sends no cookies, as most search engine crawlers do not. A loop that a browser escapes with a cookie still shows here.
Seen in a real crawl
From a crawl of Millbrook Hardware (the broken fixture), a test site from Raptor’s fixture suite.

The id is stable, and every surface uses it, so it’s the thing to search for or hand to an agent.
